installing headers(dweet, please read)

[rrv312]

hey all, i am finally attempting to install the obx 4-2-1 header on my 00 elantra tomorrow. can anyone provide any type of install steps that could ease the process? dweet, i know that you have the same ones, so i just emailed your hotmail account....thanks

Easiest if you unbolt the PS pump and pump mount from the head. Don't undo any lines, just take the pump off the bracket then remove the bracket. Also, remove the fan from the radiator (only need to remove one, you should be able to tell which one).

The one closest to the power steering pump!:lol:

we started removing the old headers, and had to stop, because the stock headers have 2 bungs, and the obx headers only have one. now i am pissed because my friend doesnt have the tools to fix the problem, and i will have to take it to a shop,,,,,this sux

Hey, screw the damn 02 sensors, i have had only one (upstream) 02 hooked up for the last 6 months no problem.. the other one is just kinda hanging there. it doesnt affect gas mileage at all. i installed the same (4-1) header on my tib, and it was really easy.. all u need to do is take off the passenger side rad. fan and then put the new header back on. email me if u have any questions. if dweet doesnt answer his emails ill talk to him for u.

wont the "check engine" light stay on if the one sensor isnt hooked up? its gotta be there for a reason or else it wouldnt be there

yeah itll throw a CEL, if u want it to go off, just get an 02 simulator. no matter if u hook up the 2nd sensor or not u might throw the same code cuz u dont have a cat. and if u move it past the 2nd cat u might still get the CEL.

[rrv312]

is there anyway to install headers and not get a CEL?

[01IMPORTSHARK]

you can 'TRY' to relocate the 2nd o2 sensor, but this doesn't always work.. its not like a bad CEL where your gonna go BOOM.. just tellin the ECU that its not reading right cuz its either dangling there or not hooked up.. just get an o2 simulator if ur worried about CEL, or take the bulb out.. u should know if something is that wrong with ur car..

hey if you're already getting a CEL just unplug the sensor and disconnect it (under the shifter surround, in the dash.. you know) that way you don't risk damaging a perfectly good 4 wire heated o2 sensor with road debris, or so.
